BACKGROUND ART

Heretofore, an organophosphorus compound, a carbamate compound, a pyrethroid compound or the like has been used as an effective ingredient for an insecticide, but as this result, some insects have had a resistance to these insecticides in recent years. Therefore, it is demanded to provide an insecticide effective for these insects having a resistance. A pyridic compound of the formula (I) or its salt is disclosed in Japanese Patent No. 2994182, JP-A-10-195072, JP-A-11-180957, WO 98/57969, WO 00/35285, WO 00/35912, WO 00/35913, WO 01/9104, WO 01/14373 and the like.

The pesticidal composition of the present invention achieves pesticidal effects against various noxious animals including anthropods such as agriculturally noxious insects, mites and the like; nematodes; and soil insects; or various diseases.

Thus, the pesticidal composition of the present invention is useful as pesticides, for example, insecticides, miticides, nematicides, soil pesticides and fungicides. For instance, it is effective against plant parasitic mites such as two-spotted spider mite (Tetranychus urticae), carmine spider mite (Tetranychus cinnabarinus), citrus red mite (Panonychus citri) or bulb mite (Rhizoglyphus echinopus); aphids such as green peach aphid (Myzus persicae) or cotton aphid (Aphis gossypii); agricultural insect pests such as diamondback moth (Plutella xylostella), cabbage armyworm (Mamestra brassicae), common cutworm (Spodoptera litura), colorado potato beetle (Leptinotarsa decemlineata), codling moth (Laspeyresia pomonella), bollworm (Heliothis zea), tobacco budworm (Heliothis virescens), boll weevil (Anthonomus grandis), gypsy moth (Lymantria dispar), cucurbit leaf beetle (Aulacophora femoralis), planthoppers, leafhoppers, scales, bugs, whiteflies, thrips, grasshoppers, anthomyiid flies, scarabs, black cutworm (Agrotis ipsilon), cutworm (Agrotis segetum) or ants; hygienic insect pests such as cockroaches or housefly (Musca domestica); stored grain insects pests such as angoumois grain moth (Sitotroga cerealella), azuki bean weevil (Callosobruchus chinensis), confused flour beetle (Tribolium confusum) or mealworms; and anthropods including household goods insect pests such as casemaking clothes moth (Tinea pellionella), black carpet beetle (Anthrenus scrophularidae) or subterranean termites; and it is also effective against plant parasitic nematodes such as root-knot nematodes, cyst nematodes, root-lesion nematodes, rice white-tip nematode (Aphelenchoides besseyi), strawberry bud nematode (Nothotylenchus acris) or pine wood nematode (Bursaphelenchus lignicolus). Furthermore, it is effective also against the soil pests. Here, the soil pests include gastropods such as slugs or snails, or isopods such as pillbugs or sowbugs. Further, it is effective against insect pests having acquired resistance to organophosphorus, carbamate and/or synthetic pyrethroid insecticides. Moreover, the composition of the present invention has excellent systemic properties, and by the application of the composition of the present invention to soil treatment, not only soil noxious insects, plant parasitic noxious mites, noxious nematodes, noxious gastropods and noxious isopods in soil but also foliage pests can be controlled.

The pesticidal composition of the present invention is applied in an active ingredient concentration of a compound of the formula (I) or its salt of from 1 to 100,000 ppm, preferably from 1 to 50,000 ppm, more preferably from 10 to 20,000 ppm, and in an active ingredient concentration of other pesticide of from 1 to 100,000 ppm, preferably from 1 to 50,000 ppm, more preferably from 10 to 20,000 ppm. The active ingredient concentration may optionally be changed depending upon the formulation, the manner, purpose, timing or place of the application and the condition of the insect pests. For instance, aquatic noxious insects can be controlled by applying a formulation having the above-mentioned concentration to the site of the outbreak, and thus, the concentration of the active ingredient in water is less than the above-mentioned range.

The amount of the application of the active ingredient per unit surface area is usually from about 1 to 50,000 g, preferably from 10 to 10,000 g, per hectare as an active ingredient of a compound of the formula (I) or its salt, and from about 1 to 50,000, preferably from 10 to 10,000 g, per hectare as an active ingredient of other pesticide. However, in a certain special case, the amount of the application may be outside the above range. Various formulations containing the compounds of the present invention or their diluted compositions may be applied by conventional methods for application which are commonly employed, such as spraying (e.g. spraying, jetting, misting, atomizing, powder or grain scattering or dispersing in water), soil application (e.g. mixing or drenching), surface application (e.g. coating, powdering or covering) or impregnation to obtain poisonous feed. Further, it is possible to feed domestic animals with a food containing the above active ingredient and to control the outbreak or growth of pests, particularly insects pests, with their excrements. Furthermore, the active ingredient may also be applied by a so-called ultra low-volume application method. In this method, the composition may be composed of 100% of the active ingredient.

An agrochemical liquid diluted to a predetermined concentration was applied by a shoulder sprayer on a 6 to 8 foliate eggplant having Thrips palmi parasitic thereon in an amount of 100 l per 10 are. The numbers of the parasitic insects were counted before treatment and 12 days-after the treatment, and a Percent Control was calculated in the same manner as in Test Example 1, and the results are shown in the following Table 4.

Also, a theoretical value of the Percent Control calculated in accordance with the Colby formula in the same manner as in Test Example 2 are shown in parenthesis in the following Table 4.

TABLE 4 Concentration (ppm) Mortality Compound No. 1 + 50 + 25 91 (79) Chlorfluozuron (E-2) Compound No. 1 50 51 Chlorfluazuron 25 58 (E-2) Number of replications: 2, 5 plants/plot

The pesticidal composition of the present invention achieves a stable high pesticidal effect, and noxious insects and other organisms can be killed by this composition. 

1. A pesticidal composition comprising a synergistically pesticidally effective amount of N-cyanomethyl-4-trifluoromethyl-3-pyridine-carboxyamide or its salt; and at least one additional insecticide selected from the group consisting of Carbofuran, Carbosulfan, Cypermethrin, Acetamiprid, Chlorfluazuron, Flufenoxuron, Pyriproxyfen, Avermectin, Buprofezin, and Fipronil.
 2. The pesticidal composition according to claim 1, wherein the additional insecticide is at least one member selected from the group consisting of Cypermethrin, Acetamiprid, Chlorfluazuron, Flufenoxuron, Pyriproxyfen, and Buprofezin.
 3. The pesticidal composition according to claim 1, wherein the additional insecticide is an IGR agent.
 4. The pesticidal composition according to claim 3, wherein the IGR agent is a benzoylurea type compound.
 5. The pesticidal composition according to claim 4, wherein the benzoylurea type compound is Chlorfluazuron and/or Flufenoxuron.
